Using itertuples() The itertuples() function is used to iterate through the rows; this function returns a tuple for each row in the DataFrame. The row's matching index value will be the first element of the tuple, and the remaining values are the row values.

Adding column breaks Place the insertion point at the beginning of the text you want to move. Select the Layout tab, then click the Breaks command. A drop-down menu will appear. Select Column from the menu. The text will move to the beginning of the column. In our example, it moved to the beginning of the next column.

You can use the for loop to iterate over columns of a DataFrame. You can use multiple methods to iterate over a pandas DataFrame like iteritems() , getitem([]) , transpose(). iterrows() , enumerate() and NumPy. asarray() function.

Conclusion There are different methods to iterate over rows and columns of the DataFrame. By using iterrows(),iteritems(),loc[],iloc[] and itertuples() we can iterate over rows of the DataFrame. We can also use apply () by creating a list of columns to iterate over columns and columns of the DataFrame.
